Here are a few guidelines for anyone wanting to post a blog.
First, you will need to register as a user on the site. I have now disabled the facility for registration, as I was having to deal with a lot of spam. So now you will have to email me first to ask for an account. If you wish to write posts, I will give you ‘Author’ status – send me an email (c.jiggins [at] zoo.cam.ac.uk). Once you have author status you can browse to the ‘site admin’ page and you will see a list of menu options on the left hand side. Choose ‘Add New’ in the Posts menu. Make sure you add a title, write your blog and press PUBLISH.
Image uploads:
If you want to post a single photo, then use the ‘YAPB Image’ tool – this will put your image into the pool for the images shown on the front page. Just look for the ‘YAPB Image’ tool at the top of the page when you add a new post (in case you are interested, it stands for ‘Yet Another Photo Blog’). Browse to the file on your computer. Once you have added any text just click on ‘Publish’ – there is no other upload button, it just uploads automatically when you click on publish. If it doesnt work, try making the image file smaller before uploading.
Alternatively, if you want to insert an image into the text of a Blog, then click on the Upload/Insert icon 
and follow the instructions. This will not appear on the front page images.
Here are some suggestions for contributions that would be of interest:
Updates on research or reviews of recent papers. Blogs on fieldwork adventures or natural history observations. Historical essays on Heliconius biology or summaries of some of the older areas of research that may not be familiar to the new generation. Updates on collaborative projects such as the genome sequencing efforts.
